This is CircuitPython 6.0.1, the second 6.0.x stable release. This release fixes regressions in BLE and FrequencyIn()
that prevent these functions from operating properly. The release also includes a considerable speedup in JSON parsing.
Download from circuitpython.org
Downloads are available from circuitpython.org. The site makes it easy to select the correct file and language for your board. The downloads page is here. Downloads are no longer available from the GitHub release pages because of the large number of files for each release. (If you see the unstable release 6.0.0-rc.2 when you browse circuitpython.org, that release is older. Use this one.)
Installation
To install follow the instructions in our new Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.
Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).
Port status
CircuitPython has a number of “ports” that are the core implementation for a variety of microcontroller families. Stability varies on a per-port basis. As of this release, atmel-samd
, nrf
, and stm
for the F4 family are stable. cxd56
, esp32s2
, and stm
for other chip families are being actively improved but may be missing functionality and have bugs. litex
and mimxrt10xx
are in an alpha state and will have bugs and missing functionality.
Fixes and improvements since 6.0.0
- _bleio:
Characteristic
andDescriptor
max_lengths can be zero. Better argument validation for
start_scan()and
start_advertising()`. #3861. Thanks @dhalbert. frequencyio.FrequencyIn()
caused a crash. #3867. Thanks @dhalbert.json
: Speed up parsing dramatically. #3728. Thanks @tannewt.
Breaking changes since 5.x
i2cslave
is nowi2cperipheral
and the class in it is changed as well.- The
stop
kwarg has been removed fromI2C.writeto()
. If no stop is desired, then usewriteto_then_readfrom
. - The default speed of
busio.I2C
andboard.I2C()
is now 100khz, not 400khz as before. Usebusio.I2C
to set the speed explicitly. _bleio.ConnectionError
has been removed. Code will now raise the nativeConnectionError
instead.- Removed
Mixer
,RawSample
, andWaveFile
fromaudioio
. They are now only available inaudiocore
. 5.x has them in both modules.

Translations
One important feature of CircuitPython is translated control and error messages. With the help of fellow open source project Weblate, we’re making it even easier to add or improve translations. Sign in with an existing account such as Github, Google or Facebook and start contributing through a simple web interface. No forks or pull requests needed!
Troubleshooting
Check out this guide for info on common problems with CircuitPython. If you are still having issues, then post to the Adafruit Support Forums and join Discord.
Assets
Builds are no longer stored as assets on this release page, because there are too many of them. Please see the Download from circuitpython.org section above.
